BODY-TREATMENT AcHInE Application filed November 19, 1928. Serial No.320,330,

This invention relates to machinesof the vibratory type which may beused either with or without belts or other appliances for givingtreatment to the body.

The objects of this invention are to provide an improved machine of thistype whlch will be simple in construction and will have the operatingparts enclosed or arranged so that there will be little danger of injuryto a person using the same; to provide a massaging machine having motordriven appliances which are actuated at a reduced speed from the motorwhereby the applicator will have proper timing to produce the bestresults; to provide a massaging machine having oscillating or vibratinglevers or arms for actuating the massaging members or for direct actionon the person to be treated; to

providea massaging machine having handles or hooks which are driven toproduce a more or less elliptical or rotary movement; and to providesuchother improvements and details of construction as will be hereinafterdescribed. i In the accompanying drawings illustrating a preferredcommercial form of my invention,

Figure 1 is a perspective view; Figure 2 is an enlarged sectional viewtaken on the line 2-2 of Figure 3; Figure 3 is a front view of the motorand operating members with parts broken away or shown in section; and

Figure 4 is a sectional view taken on the line 4-4 of Figure 3.

In the machine as shown in these drawings, I provide a base or platform5 upon which the person to be treated stands. This platform has a postor column 6 which is secured thereto and extends upwardly a. convenientdistance to support the operating mechanism. A frame or block 7 issecured to the upper end of the column by means of bolts 8 and carriesthe motor 9 which is fastened thereto by screws 10. Thebody of the motormay be secured to the post 6 or bear against the same, as shown inFigure 2. The motor shaft 11 has pulleys 12 secured to either endthereof which are engaged by belts 13 which in turn drive pulleys 14 ona countershaft 15 which has its bearings 16 in the frame or headblock 7.Eccentrics 17 are keyed or otherwise secured to the shaft 15 and arefastened to the pulleys 14 by means of screws 18, the arrangementbeingsuch that the pulleys, eccentrics and shaft. are driven in unison.The eccentrics 17 are .engaged by eccentric straps or bearings 1-9 oncranks or arms 20. The rings or bearings 19 are held in position on theeccentrics by means of disks orplates 21 which are held by screws 22 inthe ends of the shaft 15 and also by screws 18. 1

- The arms or levers 20 are provided with slots 23 for engagement withsleeves or crossheads 24 on pins 25, which pins are fastened in arms orprojections 26 extending out from the main frame 7. The outer ends ofthe arms 20 have handles or hooks 27 which may be grasped by thehandsofthe person to be treated or to which maybe attached a belt orstrap as shown at 28 or any other suitable applicators for engagementwith the body. The position of the sleeve; oribearing 24, as

, shown in the drawings, is such that it gives a substantiallyelliptical movement to the handles 27with themain axis of the ellipse ina horizontalplane. The positoin of the bearings, however, may be changedso that the, hooks or handles willhave either a circular movement, or ifdesired, an elliptical movement with the major axis in a vertical planeas will be readily understood. 7

.The frame 7 has integrally formed disks 29 at either end thereof whichare engaged by. protective guards or shields 30 which cover the pulleysand eccentrics and which are also provided with channel-shapedextensions 31 which extendover the lugs or brackets 26 andtend toprevent any accidental contact of the person with the pivotal bearingsof the arms. r The eccentrics are preferablypositioned on the shaft inopposite relation to each other so that the hooks or handles will movein opposite directionswhereby the strap'or belt 28 may be drawn back andforth over any part of the person to which it may be applied. When thedevice is to be used, the motor is started which drives the countershaftthrough the double drive which insures steady and even movement and atthe same time reduces the strains on the apparatus. The rotary movementof the countershaft is changed to a crank movement for the pivoted armsby means of the eccentrics or other suitable connections and suchmovement causes the arms to be reciprocated or moved longitudinally aswell as swung or moved up and down at either end thereof. The positionof the fulcrums or pivots 25 may be arranged to give any desiredcomponents to the-movement of the handles, which in the arrangementshown will have a substantially elliptical movement. This movement willnot 7 only transmit a longitudinal or back and placed in a vertical orsuspended position as for treating the feet and even in this positionwill have a substantial vibratory or massaging action imparted thereto.The

speed of the motor is reduced through the reduction drives so that thevibratory arms will be given a relatively slow movement or movement suchas is best adapted for physical treatment in order to produce the mostsatisfactory results.

This also'permitsthe person to be treated to grasp the handles 27 forreceiving vibratory treatment for the arms; consequently the.upperportion of the body. In place of the closed strap or belt 28, asingle strap may be applied to either one of the hooks and brought intoengagement with any desired part of the body as by being wound aroundthe same in order to give a variation in treatment.

It will be noted that the operating portions of the machine might besecured to a wall or other support instead of being ar-, ranged on apedestal and other changes may suggest themselves as coming within thescope of this invention which is set forth in the following claims, inwhich I claim:

1. In a massage machine, the combination of a main frame, means forsupporting the frame, a motor secured to the frame, pulleys mounted oneach end of the motor shaft, a countershaft mounted in said frame,pulleys on said countershaft, belts engaging with the pulleys on themotor shaft and countershaft, levers having slots therein, pins on themain frame engaging with said slots, and means actuated by the pulleyson the countershaft for giving rotary movement to the inner ends of saidlevers, the outer ends of the levers having hooks or the like.

2. A movement cure or treatment machine comprising a base for supportinga person to be treated, a column secured to the base, a main bodysecured to the column, a motor suspended from the main body, pulleys oneach end of the motor shaft, a countershaft mounted in the body, pulleyson the countershaft, belts engaging with the pulleys on the motor shaftand countershaft for driving the countershaft, eccentrics secured to thepulleys on the countershaft and also secured to the countershaft, crankarms having bearings engaging with the eccentrics and having slotsspacedfrom said bearings, bearing members secured to the frame andengaging with said slots, hooks on the outer ends of, the crank arms, anapplicator adapted to engage with the hooks, said main body havingoutwardly projecting guard members adjacent to the pulleys, and outerguard members covering the pulleys and main portions of the crank arms.a r f 7 JOHN T.
